What are BP180 and BP230?
Serum samples are analyzed by ELISA technique with recombinant BP180 and BP230. BP180 has a molecular weight of 180kD and is also called BPAG2. BP230 has a molecular weight of 230kD and is also called BPAG1. Answer. The result is given as positive or negative.
What does the BP stand for in the protein BP180?
Abstract. Bullous pemphigoid (BP) is by far the most common autoimmune blistering dermatosis that mainly occurs in the elderly. The BP180 is a transmembrane glycoprotein, which is highly immunodominant in BP.
How is pemphigus diagnosed?
Pemphigus vulgaris is an uncommon, potentially fatal, autoimmune disorder characterized by intraepidermal blisters and extensive erosions on apparently healthy skin and mucous membranes. Diagnosis is by skin biopsy with direct and indirect immunofluorescence and enzyme-linked immunosorbent assay (ELISA) testing.
Which lab studies are performed in the workup of pemphigus vulgaris?
To establish a diagnosis of pemphigus vulgaris, perform the following tests: Histopathology from the edge of a blister. Direct immunofluorescence (DIF) on normal-appearing perilesional skin.
What antibody causes pemphigus?
Pemphigus vulgaris This form is associated with the presence of IgG antibodies against desmoglein 3, with or without antidesmoglein 1 antibodies. Patients with both antibodies tend to have more severe or active disease;11 desmoglein 1 antibodies tend to decrease more rapidly on treatment than desmoglein 3 antibodies.
Which is the drug of choice for bullous pemphigoid?
The most commonly used medications are anti-inflammatory agents (eg, corticosteroids, tetracyclines, dapsone) and immunosuppressants (eg, azathioprine, methotrexate, mycophenolate mofetil, cyclophosphamide).
What diagnostic symptom is typical for pemphigus?
Pemphigus causes blisters on your skin and mucous membranes. The blisters rupture easily, leaving open sores, which may ooze and become infected.
What is the best treatment for pemphigoid?
Topical corticosteroids, systemic corticosteroids, and doxycycline are the mainstays of initial treatment for bullous pemphigoid. Additional immunomodulatory therapies are often added to minimize the adverse effects of chronic corticosteroid therapy or to augment improvement in the disease.
What causes pemphigoid?
Pemphigoid is caused by a malfunction of the immune system and results in skin rashes and blistering on the legs, arms, and abdomen. Pemphigoid can also cause blistering on the mucous membranes. Mucous membranes produce mucous that helps protect the inside of your body.
Is pemphigoid an autoimmune disease?
Pemphigus is an autoimmune disorder. Normally, your immune system produces antibodies to fight off harmful invaders, such viruses and bacteria. But in pemphigus, the body produces antibodies that damage cells of your skin and mucous membranes.
What triggers pemphigoid?
Bullous pemphigoid is caused by a problem with the immune system (the body’s defence against infection). Instead of attacking germs, it attacks and damages the skin. It’s not known why this happens. Sometimes it’s been linked to skin damage (such as sunburn) or taking certain medicines.
